Myself and my girlfriend are planning a trip through South America next year and were looking at the Falls as one of our stops. We were planning to arrive from Rio by plane and go on to Buenos Aires after. Does anyone have any recommendations for travel to and from Iguaza Falls? Had read a little bit about the sleeper buses to Buenos Aires and they seem like a good option. The flights that we had looked at so far had come up a bit pricey at £300 cheapest (Skyscanner) So we are looking at some alternatives. Any advice is appreciated! Many thanks in advance.
